Abstract: Disclosed is a method for efficient and self-aligned laser to waveguide coupling being an important step towards higher integration of opto-electronic circuits. For automatic alignment of an optical waveguide (67 - 69) to a ridge waveguide laser (50 - 52), the ridge structure (54) of the laser is transferred into the substrate (50) by etching the mirror groove. The transferred ridge structure (55) serves as base for the deposition of the waveguide layers (67 -69), their thickness being controlled during the deposition such that the waveguide core (69) is laterally and vertically aligned to the lasing active layer (51) of the laser structure (50 - 52).

Abstract: The feeding device especially for chicken farming substantially comprises a cylindrical upright distributor (4) located above a containing plate (1) and connected at the upper part thereof to a feed-carrying horizontal tubular duct (5) supported by ropes (6). The distributor (4) is moved close to the plate (1) causing a reduction of the feed (7) level in the plate (1) by lowering the tubular duct (5). In addition, the distributor (4) has a pair of vertical recesses (8) and within each of them a C-shaped flat spring (9) is accommodated thereby forming a housing (10) into which a tooth (11) present on an annulus (3) integral to the plate (1) and disposed about the distributor (4) can be snap-fitted. In this way the feed level can be simultaneously reduced in all plates (1) of the distribution line by merely lowering the horizontal duct (5). Subsequently, as the chicken size grows, it is possible to simultaneously raise all plates (1) from ground by merely lifting the duct (5) since each distributor (4) has been made integral with the plate (1) due to the snap-fitting of the annulus tooth (11) in C-shaped spring housing (10).

Abstract: La base de règles d'un système expert qui est composé d'un ensemble de règles de production comprenant des parties d'état, des parties d'action et des certitudes est hiérarchiquement résolue en unités de propositions qui ne comprennent chacune aucun opérateur logique ou qu'un seul. Puis, chaque proposition, composée d'une liste catactéristique comprenant les relations avec des propositions des hiérarchies supérieures et la certitude, est automatiquement générée. En outre, une configuration initiale d'un réseau neural, dans lequel les relations de connexcion entre les propositions correspondent à celles ayant lieu entre des neurones, est automatiquement produite selon la liste caractéristique générée. Par la suite, l'apprentissage du réseau neural créé est effectué. Ainsi, même une personne qui n'aurait aucune expertise peut effectuer de manière efficace la maintenance de la base de règles du système expert.

Abstract: Procédé et appareil servant à réduire l'usure d'une électrode dans un chalumeau à arc-plasma (14) qui se caractérisent par une réduction sensible du flux de gaz de plasma entre le chalumeau et la chambre à arc-plasma (32) comprise entre l'électrode (22) et un bec (26). La diminution de pression intervient immédiatement avant la chambre à arc-plasma (32). Il y a aussi un faible apport localisé de gaz de plasma entre la diminution de la pression et la chambre à plasma. Cet apport est suffisant pour stabiliser l'arc quand le flux de gaz est arrêté en amont de la diminution de pression et le courant de l'arc est coupé très peu de temps après. La diminution de pression est suffisamment faible pour permettre un flux de gaz de plasma approprié vers la chambre à arc-plasma (32) pendant des opérations normales, mais suffisamment forte pour isoler les gaz résiduels dans le chalumeau de la chambre à arc-plasma quand le courant de l'arc est coupé. L'appareil est de préférence un anneau de tourbillonnement (28) avec une préchambre annulaire (42) alimentée par une série de trous d'étranglement servant à faire passer les gaz dans la chambre et à réduire la pression. Une série de trous de tourbillonnement (30) servent à faire passer des gaz de la préchambre (42) dans la chambre à arc-plasma (32).

Abstract: A panel-form loudspeaker has a resonant multi-mode radiator panel which is excited at frequencies above the fundamental frequency and the coincidence frequency of the panel to provide high radiation efficiency through multi-medal motions within the panel, in contrast to the pistonic motions required of conventional loudspeakers. The radiator panel is a skinned composite with a honeycomb or similar core and must be such that it has a ratio of bending stiffness to the third power of panel mass per unit area (in mks units) of at least 10 and preferably at least 100. An aluminium skinned, aluminium honeycomb cored composite can meet this more severe criterion easily.   <IMAGE>

Abstract: A system for controlling the temperature of a lamp annealer which system comprises a group (6) of lamps (5) for heating an article to be heated, a radiation thermometer (12) for measuring the temperature of the article, and a lamp output conroller (14) for controlling the output of the lamps (5) based on the output of the thermometer (12), the controller having stored therein a target temperature control pattern. The system is adapted to effect open-loop control by controlling the lamp output according to a predetermined lamp output control pattern until the thermometer (12) reaches a specified temperature range enabling closed-loop control and not lower than the lowest temperature measurable by the thermometer (12), to compare the gradient of temperatures measured by the thermometer (12) with the gradient of the target temperature control pattern to determine the ratio of the former to the latter after the output of the thermometer (12) has reached the temperature range, to continue the open-loop control while the gradient ratio is smaller than a predetermined control change-over reference value, and to perform closed-loop control by controlling the lamp output after the gradient ratio has increased to not smaller than the reference value so that the temperature measured matches the target temperature control pattern.
